Hello,I'm evaluating ST25DV for an application and am trying to characterize max available VEH voltage. I'm using STEVAL-SMARTAG1 board, and monitoring VEH output while enabling "Energy Harvesting" feature on the "NFC Tap" app. I can't seem to get a...
Hello,Can this chip produce a constant [unmodulated] NFC field without timeout? I have a lab application where I'd like to output a constant unmodulated signal through attached NFC antenna. Based on reading the datasheet a direct command can be use...
Hello,I recently purchased the STEVAL-25R3916B board and it functions correctly with the out-of-the-box demo. However, I’ve been unable to get it working with any of the available software tools, such as the ST25R3916 Discovery GUI or ST25-PC.I’ve c...
Hi everyone,I’m currently working on integrating the ST25R3916B NFC reader into my custom hardware and would like to avoid implementing the complete driver from scratch in C/C++. Therefore, I’m trying to base my work on the X-CUBE-NFC6 software packa...
Hello everyone,I am currently using a custom NFC board based on the X-Nucleo-NFC08A1 that has the ST25R3920B MCU. I am able to perform OOB pairing (LE Secure Connections) using the example provided by ST in the software tools example. I can sucessful...
HelloI’m currently designing an NFC product using the ST25R3911B reader IC and evaluating two standard NFC antennas from Leankon for read distance performance:LK1860701 (larger size)LK1860601 (smaller size)Test Setup & Observations:Matching Circuit O...
Hi,I would like to know if it is possible to use another oscillator source other than a crystal for the ST25R300?I saw another post for the ST25R3911B, Is it possible to use a Clock Oscillator instead of Quartz crystal oscillator?, although obviously...
The X-CUBE-NFC3 zip I downloaded (v2.1.0) does not contain the CR95HF driver (Drivers/CR95HF folder missing). The package claims to support CR95HF for STM32, but only ST25R95 files are present.Impact:Cannot detect ST25TA tags using X-NUCLEO-NFC03A1 (...
I have X-Nucleo-Nfc09A1 and Nucleo-L053R8. I am trying to test the kit with X-CUBE-NFC9 software. But it gets stuck with this error:if( !st25r200CheckChipID( NULL ) ) { platformErrorHandle(); return RFAL_ERR_HW_MISMATCH; }Post edited to apply s...
